University of Washington
  Purpose

This is a 12-month, phase II, prospective, open label study, to evaluate the effect of mycophenolate mofetil (MMF) among patients on the kidney transplant list with high Panel of Reactive Antibody (PRA) levels.

On average, increasing the PRA from 0 to 50% specifically in the Washington Organ Procurement Organization (OPO) increases the waiting time from 3 to 6 years. Spontaneous decreases in the PRA rarely occur and is associated with a decreased chance for transplantation and a decreased rate of survival.

Primary Outcome Measures:
  • The Number of Subjects With a 10% Decrease in PRA Level at Month 8. [ Time Frame: Enrollment to month 8 ]

Secondary Outcome Measures:
  • The Number of Subjects With Significant Infections up to Month 12. [ Time Frame: From enrollment to month 12. ]
    The number of infections while on-study up to month 12. Subjects who's PRA decreased by 10% at month 8 and who went on to the Mycophenolate mofetil + Rituximab study were followed to month 8. Those subjects who stayed on the Mycophenolate mon-therapy study were observed for infection over 12 months or until they seperated from the study.

  • The Number of Kidney Transplant up to 12 Months. [ Time Frame: Enrollment to month 8 or month 12 post enrollment. ]
    The number of kidney transplants up to month 12. Subjects who's PRA decreased by 10% at month 8 and who went on to the Mycophenolate mofetil + Rituximab study were followed to month 8. Those subjects who stayed on the Mycophenolate mon-therapy study were observed for infection over 12 months or until they seperated from the study.

  • The Number of Pariticpants With a White Blood Cell Count Below 2.0 Thousand (Low) or Total IgG/IgM Titers Below Range (620-1490 mg/dL). [ Time Frame: Enrollment to month 12. ]
    The number of subjects with adverse hematologic effects with MMF while on-study. Subjects who's PRA decreased by 10% at month 8 and who went on to the Mycophenolate mofetil + Rituximab study were followed to month 8. Those subjects who stayed on the Mycophenolate mon-therapy study were observed for hematologic effects up to 12 months.

  • The Number of Transplants With a Negative Crossmatch at Transplant. [ Time Frame: Number of Transplants with a Negative Crossmatch. ]
    The number negative crossmatch transplants up to month 12. Positivie crossmatch transplant carries a higher risk for rejection. Subjects who's PRA decreased by 10% at month 8 and who went on to the Mycophenolate mofetil + Rituximab study were followed to month 8. Those subjects who stayed on the Mycophenolate mon-therapy study were observed for negative crossmatch transplants to 12 months.
